  1. Check the operation of the swirl control valve.

    1. Check that the valve is fully opened under normal conditions.

    2. Connect a vacuum pump to the control valve. Check that the valve is fully closed when a negative pressure of 66.7 kPa (500 mmHg, 19 in.Hg) is applied.

    3. Leave it for 1 minute and check that the vacuum pump needle does not move. If the result is not as specified, replace the intake manifold.
